If your fluid level is low this can happen. What concerns me is why is fluid level low. When your engine is cold fill your radiator and reservoir. See what happens.. You may start to get heat. Check your antifreeze everyday when cold to see if level is going down. If so you may need to replace the head gasket. Did you buy from dealer or private. If dealer they may repair, if private it's now your problem. GOOD LUCK FRIEND.

99% chance it is the blower resister located behind glove box. Squeeze glove box in and pull out.
The resistor is right behind it, dealer part cost less then $20.
Dodge has had this problem for over ten years and until recently did nothing. Now they combine fuse with resistor, suppose that will correct it?

SOURCE: Heater on driver-side blows barely warm air other vents blow cold

the most probabale cause of this would be a disfunctional hear core if you replace your heater your heater will more than likley work the the way it's supposed to

SOURCE: air conditioner not blowing cold air

go to a parts store such as Advance Auto Parts or Auto Zone and buy the A/C recharging kit they have with the rubber line and connector that connects only on the side that you need to recharge your system. If you can put air in your tires you can out freon in your a/c system.

Heater blowing cold air


If there is a internal antifreeze leak, there will be antifreeze mixed in your oil. Check your oil. If there is antifreeze in there, you probably have a bad head or base gasket. Worst case scenario is your block is cracked somewhere. Check your heater core and the lines as well. If the heater core is bad it will be leaking.
Check the thermostat housing for a leak. Sometimes
the antifreeze will leak from there, and burn on top of the exhaust instead of dripping onto the ground. Good luck

I only have heat when I step on the gas.


does the fan speed up when you step on the gas, or does it blow a consistent speed, just warmer when the engine rpms go up? If it blows faster when you step on the gas, it's just a battery or alternator issue. you start by replacing the battery then testing the alternator. on the other hand, if the fan speed is consistent and the air coming out of the vents gets warmer when you step on the gas, the issue may be with your water pump.

Be sure to keep an eye on your coolant level. If there's a leak, then it'll just get low again and return with no heat. There'll also be a chance on overheating your car if it's low on coolant.

Make sure if you're adding water, that it's DISTILLED water. It's free from impurities and will be much better for your system.

It's actually recommended to use 50/50 diution of antifreeze and distilled water. You can buy this already pre-diluted, which is easiest. Or you can buy the full mixture of antifreeze yourself and mix it 50/50 with the water.

Heater blowing clod air


the heater core behind the dash may be bad, it is the coolant tank for the heater system that is to say it is where the heat comes from. kinda pricey to have repaired at a dealership, if you can hear the fan turning but no heat, than it is a good possibility, or a vent hose has fallen off, get down and check under the dash

What are the readings on your A/C service gauges, hi and low sides? If you don't have service gauges, inexpensive ones can be purchased at stores like: Harbor Freight, Walmart, Pep Boys, etc. The gauge readings are the first step to a correct diagnosis.

Your system may be low on refrigerant. If you also have a rear heating unit, the air mixing door or water valve may not be shutting off. Your expansion valve may be bad in the rear unit.

If you can access your rear a/c, check to see if the inlet hose is hot or cold. If it is cold, you are low on refrigerant. If it is hot and the tube coming out of the expansion valve/orifice is cold, this is the way it is supposed to be. If the tube on the outlet of the evaporator is not cold, then you are low on refrigerant or the expansion valve/orifice may be bad.
